Liua shihi Liua tsinpaensis morphology adaptation systematics
Skull characteristics play an important role in the systematics of tailed salamanders. In this study, the skullsof Liua shihi and L. tsinpaensis were compared using a clearing and double-staining technique. The results showed thatin L. tsinpaensis, the vomerine tooth rows are in a “ ” shape, the length of the inner vomerine tooth series isnearly equal to that of the outer series, the vomerine tooth rows do not extend beyond the choanae, an ossified articularbone is absent, the basibranchial is rod shaped, the radial loops exhibit a figure-eight shape, the cornua has twocylindrical branches, the urohyal is rod shaped, and the end of the ceratohyal is not ossified; these features differconsiderably from those of L. shihi. The ossification of the posterior portion of the ceratohyal and the present or absentof ossified articular might represent ecological adaptation to feeding in different environments.
